What role does nitrogen play in the growth of sesame?

(Agricultural Wealth Network) Nitrogen is a major component of proteins, chlorophyll, enzymes, nucleic acids, vitamins, alkaloids, and other substances. When nitrogen supply is normal, the plants grow vigorously, and the yield is high with good quality. When the amount of nitrogen used is excessive or applied too late, it causes excessive vegetative growth and lodging, and at maturity the plants stay green and the ripening period is delayed. Disease resistance weakens, leading to reduced yield and declining quality. Conversely, when nitrogen supply is sufficient, the formation of proteins and chlorophyll in the plant is hindered, and growth and development are slow. The plants appear short and stunted, with small leaves, yellowing leaf color, and even withered yellow, showing premature aging. Therefore, rational application of nitrogen fertilizer is one of the measures to increase yield.
